Very good condition. Beautiful, crisp colorful pages with no rips, tears, folds, writing or highlighting.  One owner in over 50 years and kept in a smoke free environment.  Cover has some scuffs  but tight intact spine, square corners.  There is about a 1 inch tear at the top of the back cover (please see last two pictures) but that is the only one.  The hard paperback is strong and in good shape.  This was purchased due to the excellent information and used as a college textbook for lettering with a brush and pen.
